addendum to previous post on matrix_expression

Ok, I fixed some of my mistakes but it now appears the overloaded 
operators aren't being seen so I must be missing another header or 
something.  Once again here's the code compiled under VS.NET, debug, 
boost version 1_29_0, with the resultant error messages following.

#include <iostream>
#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/matrix_expression.hpp>

int main() 
{
    using namespace boost::numeric::ublas;

    matrix<double> m1(3, 3), m2(3, 3);

    for(unsigned int i = 0; i < std::min(m1.size1(), m2.size1()); 
++i) 
       for(unsigned int j = 0; j < std::min(m1.size2(), m2.size2()); 
++j) 
            m1(i, j) = m2(i, j) = 3 * i + j;
        
    std::cout << m1 + m2 << std::endl;

    std::cout << m1 - m2 << std::endl;

    std::cin.get();
    return EXIT_SUCCESS;
}

Thanks to all for their help!
